Local Environmental Conditions
Built-up land makes up around 35% of the area near Rose Bay, with a good deal of woodland and some open grassland. Of the allergenic trees nearby, plane tree matters most, while olive and oak also contribute. Grass pollen is significant here, and pellitory and pigweed contribute weed pollen. Compared with most places, pellitory is especially widespread here, which makes it one of the key local allergens.
Tree pollen peaks in early spring, when the weather warms to around 15°C and plane tree, olive and oak are in full flower. Grasses take over in mid-spring, with temperatures around 20°C, and their pollen lingers into mid-fall. The most intense period comes from late winter into early winter, when pellitory and pigweed are in flower.

How often is the Rose Bay pollen forecast updated?
The Rose Bay pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Rose Bay come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Rose Bay based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Rose Bay, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
